To It whom, it may concern .le it lcnown that I, subject o'tI thev King ot' Saxony, and residingr at Zwivhau, in the Kingdom of Saxony and (ierinan llnipireI` have invented certain new and useful iimprovements in or .Relating to totnry Inelosed .l'lnginess, ot whieh the t'ollowing is a speeilie-ation.

M y invention relntes to rotary inelosed enginesl and has t'or its ohjevt to provide :l rotary inrloeied engine with an internally arranged displacing nivinher piston or the like. 'this invlosed engine van he uned as a priiue inorer in employing steam, gasenor other inotire media. or a a hlower or a delreriY inaehine lor liquid. l'or eoinprefsing gases-i or lor ere-at ing a \eruuin.

Fig. (3 shows the crasingwith the distrihuting members in elevation. Fig. I shows the casing with s modiiiecl form of the flistributing members in cross-section. Fig. 8 illustrates e. constructionel 'forni of the in 5 closed engine in longitudinal section in which two vseperate inclosetl engines are srienged on a common shuit, one oi there serving es' a motor and the other as u pump. Fig. 9 illustrates e constructional forni ci' 1o the inclosed engine in cross-section inl which the two high pressure cylinders sind the two low pressure cylinders src connected one with the other hyu common. intermediate receiver. Fig. 10 is a. section of the cut-oil' members connecting the intermediate receiver chambers, in which the conununicstion between the receiver chambers is cut oft, While communication between one of the receiver chambers and the low pressure Weste steam pipe und communication between the other receiver chamber and the lire .st-cum pipe is established. Fig. il illustrates in section c modified construction of 'the cut-cfr members connecting,7 the intermediate recciver chambers.

The inclosed enfrine consists oi" sninner solid cylinder l which is combined axially with an outer hollenr c linder 2 between which a hollowinternie iste cylinder 3 is fixed (see Fig. l). rl`he inner solid cylinder l und the outer hollow cylinder 2 .rotate 'respectively within and shout the hollow cylinder 3 und remain always in partial contact with this cylinder. A blade 4 is 36 piroted on the inner cylinder l und is displaccuhly guided in ai radial cut in the stationery intermediate cylinder 3. The blade fits snugly against the side Walls of the turn. cylinders l und 2, z'. e., extends from the 40 cylinder l up to the inner periphery of tl: hollow cylinder 2 concentric with the cylin der l curl divides the inclosed speces in such e manner that the motive medium to bc supplied (liquids, gases und the like) is l5 separated from the motive niediuni to he discharged. Consequently', the engine can be employed either es o motor or as s pump. The urrangementfof the distributing members adopted to control the edmissionmlnd exlmust of the motive medium depcndsgupon the particular employment of the engine in view. As this engine embodies the continuous current principle, when it is used es a motor the exhaust members con be dispensed with While when it is em )loyed as a pump, compressor or the like, t e admission members are unnecessary.

Live steam enters through the connecting branch 5 provided on the engine casing; it flows through the passuge- Gfprovided in the intermediate cylinder es ier :is the vulve v7..urriniged in this cylinder, through which it passes into the Workingchumber 8 located between the cylinder 3 und the inner solid 5 cylinder il. .Bytliessction or the stoom the inner solid cylinder l is driven around with the shsi't 9. After one revolution of the engine, z'. e. of the rotary element thereof, the live steam comes opposite the inner cylinder 1 by which it is forced through the port l() into the receiver ll. The' steam then passes through the duct l). which is open to .it over thc rotary chamber l-l located between the intermediate cylinder 3 und the outer cylinder 2 in which chsniloer the steam produces a rotary effect and rotating the outer hollow cylinder 2, `which like the cylinder l. is fixed to the shcit 9, after 'which the steam escapes throurh the passage l5 und the connecting brunch 16 into the atmosphere or into a' condenser. When the engine is employed as o pump or a compressor the direction of rotation und the physical action is or" course reversed.

The principal advantages obtained with 'this form oli' engines are es follows: The blade fl is doubly utilized in both directions, which is not the case with machines of a similar type es hitherto constmctecl; the engine can be utilized in various Weysfor the purpose of obtaining u compound (tufo-V stsyje) or o. twin (duplex single-siege) cilfect;A the passage G in. the intermediate cylinder 3 can be utilized Vfor heating or cooling purposes according to the purpose for which the engine is to be employed; the inner high pressure chambers are in closed by the outer low pressure chambers wherehy (and thisispzzirticulurly advantageous in the ciiscdi'f `steam engines) rudiotionenliyhect lis either avoided o1' greatly reduced. It should also be noted that the rotary members or the rotar cylinders can be formed as n. counter Weig t or provided with u counter weight for com ensating purposes. The slides or blades un also the passages or chumoers con he muli tiplied in accordance with requirements Without any diiiculty.

The inclosed engine illustrated in Fig. E, which is also constructed us u steam engine, consists of two similar inclosed engines A and B arranged side hy side in a common casing; l?. By this means the axial pressure produced in one engine is balanced by the axial pressure in the other engine.

ln the construction or the inclosed engine illustrated in Fig. 4, the intermediate cylinder 3 is provided with partitions. 'These partitions 18 and i9 seperate the admission and exhaust ports of the two incloseol englues one from the other. tion oi' the admission und exhaust ports ot the two inclosed engines, the engines can he used with advantage for separate action, for example for tWostege action, that is to say for compounding, or 'they mcy serve different purposes one being employed os A s motor and the other es e. pump or the like.
